About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X135-100S
The AirTAC SAIJ80X135-100-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to dial back the nominal 135 mm travel by up to 100 mm. This creates a highly flexible 35-135 mm usable travel window, letting you fine-tune the retract end-position during commissioning without swapping out the physical cylinder. It delivers a robust 2513 N push force at 0.5 MPa, making it well-suited for moderate to heavy actuation tasks.
Equipped with a -S magnet, this unit supports AirTAC CMSE reed and DMSE electronic sensors housed within the dual-side extruded aluminum barrel grooves. The M20x1.5 piston rod and G3/8 port provide durable mechanical interfaces, while the rear stopper serves purely as a travel deceleration point. It does not hold the load without live air pressure, so applications requiring true load-holding should utilize an external rod lock or explore SAIL and BSAI series cylinders.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X135-100S Is Used
Variable End-Stop Setup
Dial in the retract distance anywhere from 35 to 135 mm during machine commissioning to perfectly align product pushers without machining new hard stops.
Product Size Changeover
Quickly adapt a packaging line to different carton lengths by rotating the rear adjuster screw, shifting the cylinder's effective stroke window on the fly.
Deceleration Tuning
Leverage the 100 mm adjustment range alongside the 36 mm variable air cushion to safely slow heavier 2513 N loads at the precise end of travel.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X135-100S the Right Cylinder?
Choose this SAIJ80X135-100-S variant when your machine setup requires extreme adjustability over end-stops, as the 100 mm trim range provides massive flexibility for product changeovers. If your process only requires a fixed 135 mm stroke without end-tuning, the standard SAI80X135 is a simpler choice. For lighter duty at the same travel, stepping down to a 63 mm bore drops the 0.5 MPa push force to 1559 N, whereas moving up to a 100 mm bore increases it to 3927 N.
Because the nominal stroke is 135 mm, an external guide is not strictly mandated, but the 25 mm carbon steel rod helps manage moderate side loads. The mounting footprint is dimensionally interchangeable with ISO 15552 cylinders, utilizing a reduced SAIJ mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Configuration details include PT tapered port threads, an M20x1.5 rod, and standard 36 mm air cushions at both ends.

Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ80 Adjustable Cylinder SAIJ80X135-100S FAQ
The rear external stopper screw allows you to shorten the effective stroke by up to 100 mm. This transforms the nominal 135 mm stroke into a highly flexible 35-135 mm usable travel window, enabling exact end-position tuning without adding external stops.
Operating at 0.5 MPa, the SAIJ80X135-100-S generates 2513 N of push force and 2268 N of pull force. At the maximum 1.0 MPa operating pressure, it can deliver up to 513 kgf.
